Merritt was activated as a COVID-19 replacement for Sunday's Week 17 road battle against the Bills.
Miami will be without Ryan Fitzpatrick for Week 17 given his positive COVID-19 result from Thursday. Merritt swings up to the active roster as a late addition, aligning the 23-year-old for his second game appearance of 2020. He fielded one snap on offense and seven more on special teams during his NFL debut Week 9 against Arizona.
